Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To form a thick silicon oxide film on the surface of a silicon semiconductor substrate. SOLUTION: A first silicon oxide film 7 thinner than a target is formed on the surface of the silicon semiconductor substrate 1 by thermal oxidation. A first polycrystalline silicon film 8 is formed on the first silicon oxide film 7. Then, the first polycrystalline silicon film 8 is oxidized and oxide is formed. Then, the oxide and the first silicon oxide film 7 are integrated so as to form the second silicon oxide film thicker than the first silicon oxide film 7. A second polycrystalline silicon film is formed on the second silicon oxide film and they are oxidized. Thus, a third silicon oxide film which is furthermore thicker is obtained.

IPC: G01N11/16
Filed: 1991-11-07
Abstract: PURPOSE:To measure the apparent viscosity of a non-Newtonian fluid under the same condition by measuring vibration force necessary for obtaining a definite amplitude value and calculating viscosity by the control of the amplitude value. CONSTITUTION:A current is supplied to an electromagnetic coil 4 so that responsive plates 1a, 1b are vibrated so as to obtain an amplitude value X0 and vibration force is applied to the responsive plates 1a, 1b. The amplitude value due to the vibration force is detected by a displacement sensor 6 and the signal of the amplitude value X is compared with a reference amplitude value by a comparison circuit 14 through an amplifier 12. When the amplitude value X is smaller than the reference amplitude value, vibration force is applied to the coil 4 by a control circuit 15 and, when said value X is larger than the reference amplitude value, a current is reduced by an automatic attenuator. When the responsive plates 1a, 1b become a state vibrated in the amplitude value X0, a current value is detected by a current detector 11 and compared with a calibration curve preliminarily obtained from a sample cleared in its viscosity to calculate viscosity.

IPC: G05F1/70
Filed: 1992-10-29
Abstract: PURPOSE:To produce the invalid power of cycloconverter as much as possible during a motor is stopped and to suppress the voltage rise by passing a circulating current to each phase of a transformer secondary winding rating. CONSTITUTION:Primary current Iu, Iu, and IW of a transformer 1 corresponding to the U-W phases of the motor are detected by current detecting devices 11, 12 and 13.

Title: Voice dialing device
Inventor: KAWAMOTO TOSHIKI
IPC: G10L15/00
Filed: 1988-11-18
Abstract: PURPOSE:To prevent destruction of standard patterns for recognition at the automatic updating time by registering the just inputted voice pattern as the 2nd standard pattern corresponding to the just dialed telephone number when the candidate for recognition of the 2nd rank or lower is selected and transmitted after the input voice of the 1st rank is recognized. CONSTITUTION:When it is discriminated that the 1st candidate of recognized results does not correspond to an aimed called subscribed, the talker calls the 2nd candidate of the recognized results by pressing the retrieval switch of a keyboard 7. When the talker calls the 2nd candidate, a control section 4 causes the standard pattern for synthesization corresponding to the 2nd candidate to be read out from a standard pattern storing section 6 for synthesization and to be outputted from a handset 1 after the pattern is converted into synthesized voices. Thereafter, the control section 4 once more detects whether or not the cancel switch or retrieval switch of the keyboard 7 is pressed. When it is not detected for a fixed period of time, the telephone number corresponding to the recognized result is read out from a telephone number storing section 8 and transmitted from a transmission circuit 9. Therefore, the standard pattern for recognition is not destroyed by updating and the recognition can be performed smoothly from the next time.

Abstract: PURPOSE:To make thin only a channel portion and its vicinities and also to provide an LDD structure by forming a gate electrode on a polycrystalline silicon layer having a thicker layer at a source-drain portion than a channel portion and its vicinities on a substrate and by filling the polycrystalline silicon layer with the impurities at an accelerated voltage. CONSTITUTION:An island of a polycrystalline silicon film 2 and a gate oxide film 3 as a gate insulation layer are formed in such a manner that the layer thickness of a source portion 9 and a drain portion 10 becomes larger than that of a channel portion 11 and its vicinities on a quartz substrate 1. After performing the doping of phosphorus of a high concentration, a gate electrode 4 is formed. Next, by using an ion implantation apparatus with the gate electrode 4 as a mask, arsenic of a low concentration is first injected at a predetermined accelerated voltage and in succession arsenic of a high concentration is fully injected at a accelerated voltage higher than that of the preceding process. As a result, the arsenic has a low concentration at the portion 12 between the channel portion and the source portion and at the portion 13 between the channel portion and drain portion, thereby providing an LDD region 8 having a gentle concentration gradient.

IPC: B66F17/00
Filed: 1987-11-19
Abstract: PURPOSE: To provide a certain lifting-up/down control by providing a digital encoder, a rotational encoder, an up-down counter, a digital comparator, and an initial reset circuit. CONSTITUTION: By changeover-controlling rotation of a motor 21 in the normal or reverse direction, an upper column 13 rises or falls, and height of a stand is adjusted. When a power switch 42 of an initial reset circuit 41 is operated, the upper column 13 first falls to a lower limit position to clear an up-down counter 39, and again rises while counting rotation frequencies. Thus, a setting position of a digital encoder 37, a count setting signal of the counter 39, and a height position of the upper column 13 are respectively matched, and therefore, a certain lifting-up/down control is performed. Therefore, when these corresponding relations are impaired by manual adjustment of the upper column 13, or storing data in the counter 39 is deleted by powering off, precise corresponding relations are set again.

Abstract: PURPOSE:To prevent a bonded part from being stripped off and to eliminate an insufficiency of a bonding strength by a method wherein a pad electrode part of an IC is formed of an electrolytic or electroless plated layer of Au, Cu, Ni, Co, Pd, a solder or the like.
